PERATION
The Quartz-G3 sounder is a high specification external warning device for use in intruder, hold-up or other
alarm systems, fully meeting the requirements for EN50131-4 at Security Grade 3 and Environmental Class
IV.
The Quartz-G3
sounder is used for notification of an alarm condition as generated within an intruder, hold-
up or other alarm system. In response to commands from the alarm system control panel, the Quartz-G3
will emit a high intensity sound and/or operate a visual flash.
The Quartz-G3
will detect any attempt to gain unauthorised access to the sounder by removal of the
cover, or any attempt to remove it away from its mounting surface. This will generate a tamper signal
which is normally fed back to the alarm control panel. Integrity of the Trigger command (Ring Line)
connection is constantly monitored and will cause the unit to self-activate and report a tamper to the
control panel if loss of connection is detected.
The Quartz-G3
is classified a self powered sounder and has an on-board battery which is recharged via the
external power source. This battery is used to operate the sounder if the external power is removed. The
Quartz-G3
will self actuate in the event that a tamper condition is detected or the external power to the
sounder is removed.
Every 24 hours the Quartz-G3 performs a self test to check the integrity of its on-board battery, its battery
charging circuit and its piezo transducers. If an error condition is detected, a fault signal is generated. This
is normally connected back to the control panel. An on-board diagnostic LED guides the maintenance
engineer to the source(s) of the fault.
To assist with commissioning, the Quartz-G3 has an Engineer Mode to provide silent start-up and Tamper
Tones that indicate the correct closure of the tamper detection switches.
Two Comfort LEDs are used to provide a heart-beat type visual indication when the Quartz-G3 is not
sounding.

NFORMATION
Tamper Circuit for Single or Multiple Cascade Installations
For single sounder installations link TS to H- and connect TR to the control panel Tamper Return input.
(See Fig. 2).
In cascade installations with two or more sounders, the TS (Tamper Source) will normally be connected to
the TR (Tamper Return) of the next sounder except for the last unit which will have TS linked to H-. (See
Fig. 3)
A Tamper signal will be generated when ANY of the following conditions exist:
- Cover removed
- Removed from mounting surface
- Connection to R- is lost
- H+ or H- power connections lost
- ENG input taken high (e.g.: to H+)
Engineer Mode
This selects silent start-up and silent maintenance. The ENG input may be brought back to the control
panel and connected to a programmable output. Switching this control panel output high when
maintenance is required will prevent the sounder from self activating when the cover is removed or R-
